Research On Knowledge Organization And Driven Mechanism Based On Cellular Automata Oriented To Design Process

Complex mechanical product is a complex system that is a set of multi-unittechnology in one and have overall function, it’s design process is coupling processwhich controlled by mechanical, electrical, hydraulic and other multi-process,multi-source, multi-component, multi-disciplinary, complex electromechanicalproduct’s design knowledge is the core of product design, it relates to multi-field,multi-design parameters, multi-objective design and other aspects, traditional designmethods and knowledge management methods are difficult to obtain an accurate andeffective knowledge, and it can not achieve knowledge reuse. In this paper, we takethe design process of complex mechanical products as object of the research, andconsider the multidisciplinary collaborative design issues of the design process ofcomplex electromechanical product, and we systematic research knowledge modelingand reuse methods for complex products, and propose design-oriented knowledgeorganization and driving mechanism. Specific studies are as follow:（1）The study of knowledge element analysis and construction technology forcomplex product. Orient unit, ecological knowledge organization system, and base onreusable technology to build multidisciplinary collaborative knowledge managementand organization system, and take use of object-oriented thinking, use ontologymodeling language encapsulated design knowledge in various fields, re-organize anddescribe the knowledge, models and process for complex product integrated analysisprocess, and formate knowledge units, describe the design knowledge comprehensiveand standardization, combine with bulb turbine design knowledge for modeling.（2）On the basis of analyzing the insufficient of the exiting knowledgeorganization methods, we propose complex product knowledge units self-organizingclustering methods based on cellular automata. Introduce the cellular automata model,and cluster a large number of heterogeneous knowledge, divide the knowledgereasonable. Verify the algorithm by using of hydro design knowledge.（3）Finally, based on the proposed design-oriented knowledge organization anddriving mechanism, we design and develop the design knowledge managementplatform, and put the design and development of hydroelectric as example.The results of this study to establish a product integration, ecological knowledge model and improve the reuse and inheritance of design knowledge, enhance theanalysis efficiency of complex electromechanical product design process, and thenexpand the theory of complex mechanical product intelligent design.
